If you rely on your iPhone to keep you on time for your reoccurring appointments, then you should be sure to read this.

According to news around the web, the current version of iOS for the iPhone has a small bug when it comes to going off Daylight Savings Time (DST). Now while the iPhone clock makes the proper time adjustment to fall back when the DST adjustment occurs, apparently some iPhone alarm settings are not making that same time transition to fall back one hour. The iPhone alarm bug was recently discovered in Australia during their DST transition, but has now been reported in Europe when the time change affected them as well.

As we are coming up on the North American switch from Daylight Savings Time to Standard Time on November 7th, chances are good the iPhone alarm bug will hit here as well. As of now there is word from Apple on a fix to this issue, but we are not sure when. Just to be safe, you may want to double-check your alarm times next Monday or better still, have a backup alarm system in place.

Double checking won’t help. My alarm was set for 0646 but sounded at 0746. The clock was set correctly and updated automatically Sunday morning. It worked fine on Sunday morning but not Monday. So annoying; first time iOS has let me down in >3yrs. :-( Recommend a backup clock or those who haven’t switched from summer time yet.

Happened to me on my iPhone 4 in the UK Monday morning. Luckily I was thrown out by the clock change and was wide awake the time my alarm was meant to go off :)

Since it happened here in Australia for so long it has been such a pain to have to remember to set my alarm each day. Not happy.
